Pattern search in sales data / data science / statistics


I need to find pattern in sales data of local store sites. I have two data sets:

1) store details (like average income at the catchment area)

2) all sales data on product level (and merchandise category link) of each store over the period of 1 year

The question here is: Can we determine any patterns for the stores? E.g. do stores in a high income area are increasing the prices more than others?

My idea is to proceed as follows (across all stores):

Division of the data records into time periods (I suggest calendar weeks, as this is also how pricing takes place)

For each product group (and then for each product):

- Determination of the average price per product of this category (sum of all individual prices / number of products)

- Determination of the average price per product (which should be stable for one week)

Comparison of the branches to each other

- Determination of a statistical significance1 in case of deviation or equality

- Comparison and pattern formation with market data

- Doing statistical tests on that

- Drawing up result hypotheses

For any proposal: State with what tool/programming language you want to work! (R, Python, Matlab, etc...)
